The Rainmax Injection Well System is the most beneficial and cost-effective technique for large roof areas (townships, gated communities & apartment buildings) to ensure constant supply of groundwater without depending on water tankers. This system has the ability to facilitate borewell recharge or groundwater recharge with 80,000 – 1,00,000 litres of water per hour. This means that 1 season of average rainfall will provide 8,00,000 – 10,00,000 litres of water for the domestic needs of an apartment building of 50 flats (10,000 sq. ft. rooftop area).
